Who called from 3864474875

This was an auto-dialer call that was trying to sign up people for medical and dental benefits, but didn't state their company name.  The auto-dialer didn't differential if it had connected to a live person or my voicemail, and had left their lengthy call on my voicemail.

I didn't recognize the # so I didn't answer it.  Apparently it was a good thing I didn't.  They also did not leave a message.  Don't waste my minutes!
